TheMCP2515DM-PCTL是一个MCP2515 CAN控制器 PICtail demo电路板 implements a simple CAN bus using two nodes. One node uses the MCP2515 st和alone CAN控制器和the other node uses the MCP25020 CAN I/O expander. Each node utilises one input (push button)和one output (LED). The电路板s demonstrate a simple, inexpensive implementation of a CAN bus. The MCP2515 node transmits its input (push button) information at regular intervals和request input (push button) information from the MCP25020 at regular intervals. An LED on each node reflects the state of the other node's push button.
